Laburnum × watereri 'Vossii'
- Position: full sun
- Soil: well-drained soil
- Rate of growth: fast-growing
- Flowering period: May to June
- Hardiness: fully hardy
A spreading tree with fine, dark green foliage, cut into oval leaflets. But it is for the long racemes of brilliant, golden-yellow flowers that this tree deserves a place in the garden. In late spring and early summer, it is smothered with pea-like chains of flowers, often up to 60cm (24in) long, followed by a light crop of poisonous seeds. It grows quickly and looks spectacular trained over a pergola or planted as a specimen tree in a small garden.
- Garden care: When planting, incoporate lots of well-rotted manure or garden compost into the planting hole and stake firmly. Laburnums dont need much pruning, but you may want to remove any diseased or crossing branches. It is essential that any pruning work is carried out between late summer to mid winter as the sap will 'bleed' heavily at other times.
- CAUTION toxic if eaten

Q:This year we perchased a Laburnham tree, it has flowered during June, but now we have noticed that something has been eating the leaves and the leaves are turning dry and brown.We have sprayed with an anti bug spray, but so far no improvement.Any idea of the cause, and what should we do next.Asked on 7/6/2014 by Ragged Robin from Wiltshire
This tree can sometimes be affected by leaf miners. These burrow between the leaf surfaces and can eventually make the whole leaf look brown. As it is still a small tree it will be relatively easy to control as you should either squash the miners (they are actually moth larvae) as soon as they appear, or remove the affected foliage. You can also spray with an insecticide containing bifenthrin or pyrethrin.Answered on 7/8/2014 by helen from crocus
Greetings Crocus, I need advise about my Laburnum, please. 12 years ago I purchased a Laburnum and was reassures by a Garden Centre that it would only grow to 2-3 metres It is much taller than that now, definitely 8 metres! Consequently it is blocking out the light from the downstairs rooms. Help! It is quite stunning when in bloom, as you can imagine. The Garden Centres have conflicting advise about what I should do. I would really like to know if I can prune it back now by about 3 metres as we are in October. Do you think I would stimulate rapid growth as a result of this action? I would appreciate your valued reply, Thank you ElizabethAsked on 10/16/2009 by E M MAJOR
A:Thanks very much Helen. I will give it a go, but I fear my laburnum is the vigorous type. We will see what happens Many thanks ElizabethAnswered on 10/19/2009 by E M MAJOR
A:Hello Elizabeth, It is difficult to advise on how the tree will respond without knowing which type of Laburnum you have. Some are vigorous, so even if you do cut it back it is likely to put on lots of new growth next spring, so if it is too big for the allocated spot, then you should really remove it and plant something better suited. If however you would like to give it a go, then the best time to prune is from late summer to before mid winter, but most rarely cope well with drastic pruning. I hope this helps.

Q:Leaf problem on new tree-will it spread to other trees?
Hi, I purchased two Acer plat. 'Crimson Sentry' trees in April of this year and have noticed a white powdery substance has taken hold on the leaves of both trees. Initially I thought it would go away but it has spread to almost every leaf on both trees. Please can you offer any help on what this is and how I can get rid of it. Also, is it likely to affect the other two trees I purchased at the same time (Laburnum ?? watereri 'Vossii' and Robinia pseudoacacia 'Frisia'). Many thanks AmandaAsked on 9/1/2009 by Amanda Button
A:Hello Amanda, Acer plat. 'Crimson Sentry' trees are prone to powdery mildew, which would fit your description - just click on the following link for more information. http://www.crocus.co.uk/pestsanddiseases/_//top12/Powdery%20mildew/ArticleID.1174 The Robinia is unlikely to be affected by it, but the Laburnum is also prone occasionally. I hope this helps. Helen Plant DoctorAnswered on 9/4/2009 by Crocus Helpdesk
Q:Summer flowering tree
Hello, I am looking for a tree that can grow as tall as 8ft-10ft and flowers for most of the summer, or even one that flowers in the winter. I am looking to add a large tree with colourful flowers to my garden - I do love the Laburnum x watereri 'Vossii' but it only flowers from May to June I believe. Can you recommend at suitable tree? Regards LauraAsked on 7/5/2009 by LAURA BLIZARD
A:Hello Laura, Even a miniature tree will get taller than 8-10ft, so I suspect you may be looking for a shrub, which are generally more compact. The ones that will flower for months on end throughout summer are either Buddlejas or Lavatera. I'm afraid I don't know of any trees (no matter what size) that will match them.Answered on 7/8/2009 by Crocus Helpdesk
Late summer is the best time to prune many midsummer-flowering shrubs to keep them vigorous and flowering well. It is also the ideal time to prune several trees that are prone to bleeding if pruned at other times, and it’s not too late to complete the pruRead full article
October sees the start of the dormant season which is the best time to prune lots of deciduous garden trees. You can prune newly planted trees to remove any damaged growth and help balance the shape of the canopy as well as maintain a dominant main leaderRead full article
